tubing question

the thing is that i can either get clear flex (10 feet) for 15 dollars, tygon tubing (10 feet) for 25 dollars but in my country, i can get this tubing that IS definetely worse then those two above (because when i bend it, the top part gets all flat.. well u know right?) but hte PRICE IS INCREDIBLE.. i have 2 meters of it that i'm using for an experiment.. on a crappy crappy ultra crappy pump about 450 liters per hour.. but there are no problems that i have been expiriencing..
the cost for 2 meters of it is about 70 cents

so..which of the 3 should i obtain??

and also.. water addictives..
should i get water wetter?
or this one

and also.. wouldn't the color of a water dye be affected by the color of the water addictive??
like.. the water wetter is red, and water dye is.. like.. yellow, would the water in the tubes (without UV lights) be wierd???

bump

The Clearflex is just as good as the Tygon but cheaper. I don't know about the SuperCool but I ordered it so once I get it setup I'll post about it.

k thx

I bet the amount of water additive added to the amount of water in the setup would be negligible.

oh
